6.5.2 Rated frequency
(uF.0) and Boost
(uF.1)
The voltage/frequency characteristic (U/f) is adjusted with the rated frequency (uF.0)
and the Boost (uF.1). The rated frequency adjusts the frequency at which 100 %
modulation depth (~input voltage) are achieved. The boost adjusts the output voltage
to 0 Hz. Depending on uF.10 the modulation limit can be further increased in this stage
up to 200 % (see Fig. 6.5.2).
uF.0 =0.0000...400.00 Hz; Default = 50 Hz

6.5.4 Delta Boost (uF.4/
uF.5)
The Delta-Boost is a time-limited Boost used to overcome large breakaway torques.
The Delta-Boost acts adding to the Boost; but the sum is limited to 25.5 %.

6.5.3 Additional Rated
Point (uF.2/uF.3)
To adapt the U/f-characteristic to special conditions an additional point of support can
be specified with uF.2 and uF.3. uF.2 defines the frequency and uF.3 the voltage. At
uF.2 = 0 Hz the adjustment is ignored.
